AUTOIEATIC SASH-LOCK FOR FIREPROOF WINDOWS.

To all whom it may concern:

Be it known that I, Ozu A. Essie, a citizen of the United States, residing at Canton, in the county oi Stark and State of Ohio, have invented certain new and useful Improvements in Automatic Sash-Locks for Fireproof l/Vindows and I do hereby declare that the following is a full, clear, and exact description oi the same, reference being had to the accompanying drawing, making a part of this specification, and to the numerals of reference marked thereon, in which- Figure 1 is a vertical section of the upper and lower window sashes, showing the lower window sash in locked position with reference to the window frame and the upper sash turned upon its pivotal point and in its unlocked position. Fig. 2 is a 'front elevation of a window frame and the window sashes, showing the window sash open and the lower window sash closed and locked, the position of the sashes being similar to those shown in Fig. 1. Fig. 3 is a detached view of the chambered lock plate and the striking lugs or anges designed to be attached to the transom bar.

The present invention has relation to automatic sash lock for hre prooi windows de signed to lock the upper and lower sash rails and where two independent window sashes are employed to lock the upper and lower sash rails of each window sash... rl`his object is brought about by the construction and arrangement of the different parts hereinafter described and particularly pointed out in the claims.

Similar numerals of reference indicate cor.- responding parts in all the iigures of the drawings.

In the accompanying drawings, l represents the lower sash rail of the lower window sash and 2 the upper sash rail of the lower window sash, which sash rails are held in proper relative position by the vertical sash rails 3 of thewindow sash proper. The sash rails 4 and 5 are similar to the sash rails 1 and 2 and constitute the horizontal rails of the upper window sash proper. lBetween the top sashrail 2 of the lower window sash and the lower sash rail 4 of the upper window sash is located the transom bar 6, which is attached to the window frame at its ends in any convenient and well known manner. To the lower sash rail 1 and to the lower sash rail 4 are securely attached the frames or Specification of Letters Patent.

housings 7, to which frames or housings are pivotally attached the locking dogs 8, which locking dogs are provided with the curved lips or projections 9 and 10, which lips are spaced apart for the purpose hereinafter described. The locking dogs 8 are also provided with the V-shaped notches 11, and the stop flanges or lugs 12. Directly above the locking dogs 8 are the gravity lock levers 13, which are pivoted to the housings 7. The gravity lock levers 13 are provided with the toothed projections 14, which are for the purpose of engaging the V-shaped notches 11, when said locking lever is in the position illustrated in the lower portion of Fig. 1, and when in such position the lower sash rail is locked against movement by reason oi the lips 9 and 10 beinO1 located upon opposite sides of the lock pate or Yflange 15, which lock plate or flange is formed integralpwith the base 16, which base is secured to the window sill 17 in any convenient and well known manner. To the upper sash rails 2 and 5 are secured the housings 1S, to which housings are pivotally attached the upper sash rail locking dogs 19 and directly below said locking dogs 19 are located the gravity lock levers 20. The locking dogs 19 are provided with the locking lugs 21, which locking lugs are designed to enter the recesses or chambers 22 and 23. The chamber 23 being formed by cutting an aperture in the sheet metal cap 24 oi the window 'frame proper and covering said aperture by the housing 25. The lower chamber being formed in the combined strike plate and catch plate 26. The locking dogs 19 are each provided with the upward curved striking lugs 27, which striking lugs are for the purpose of actuating the locking dogs 19 as hereinafter described. For the purpose ol' limiting the rocking movement of the lockingvdogs 19, the housings are provided with the stop pins 28, which stop pins are located between the shoulders 29 and the flanges 30.

It will be understood that if there was nothing to limit the locking movement of the locking dogs they would swing outfolposif tion during the time the window sashes are moved upon their pivotal points, or in other lows: action ol the upper locking dog 19 will be described. Assuming that the window sash is open and vit is desired to close and lock the upper window sash the locking dogs being in the position illustrated in the top of 1, as the top ol' the window sash is brought toward and under the cap 24 the striking lug 27 will come into engagement with4 the front l'ace ol' the cap 211 and tilt the inner end ol' said4 locking dog upward and move the lock ing lug 21 upward and into the aperture and as the dog 19 is moved upward, the gravity lever 120 will be released and fall into the position illustrated in the middle portion ol Fig. 1, thereby locking the dog 1.9 against downward movement, and of course locking the window sash.

For the purpose of allowing the locking dogs` 19 to assume a lowered position or the position. illustrated in the upper portion oi Fig. 1:, said locking dog-s are provided with the cut out portions 31, and into which cut out portions the projecting .lugs 32 formed uponthe lock lever 20 are permitted to en ter. In Fig. 1 the locking gravity levers 20,

are shown in their upper and lower positions and the locking dogs in their locked and unlocked positions, the lower locking dog 19 being actuated by the strike plate 33 in substantially the same. manner. that the upper locking dog is actuated by the front 'face of the cap 2 4.

It will be understood that when the win dow sashis locked at its top and bottom it is necessary to release the locking devices con.- nected-to the to p and bottom rails of the sash frames proper and in order to simultaneously unlock the upper sash rail and the lower sash rail, it is necessary to elevate the gravity locking levers 13 and 20, and in order to provide for simultaneously elevating said locking levers and simultaneously releasing the lock.

ing dogs 8 and 19, the actuating chain 34 is provided, which actuating chain is connected to the gravity locking lever 1.3 at its nlower endl and thence extended upward and through the loop 35 and thence downward to a point easy of access and provided with the pull ring 36.

It will be understood that by a downward pull upon the ring 36 the levers 20 and 1.3 will be simultaneously elevated at their outer points and the locking dogs 3. and 19 be released-at which time the window` sash proper is free to move upon its pivotal point. After the gravity locking lever 13 has been elevated and the tooth 1.4 detachedfroin the V-shaped notch 11 the locking dog 8 will be rocked upon its pivotal point by reason of the curved lip 10 coming into engagement with the iiange 15 andthe locking lever 13 held in its elevated position. For theV purpose of assisting` in bringingA the locking dogs 8 in the position illustratedy in the upper portion of For the purpose oi' clcarness the l Fig. 1, said locking dogs are provided with the weighted ends 37, which weighted ends assist in bringing said locking dogs in the position to hold the gravity locking levers 13 in their elevated position.

.lt will be umlcrstoed that the locking dogs 3 should be stopped at such a point that they will be rocked by the lips 9 when the window is closed and locked and 'for the purpose oi stopping the locking dogs, at a point where the lips 9 will come in proper engagement with the i'langes 15 and 40, the stop llanges 12 are provided, whichstop flangesstrike the toothed proiections 14.

After the top and bottom rails have been unlocked by thc pulling of the chain31, a `further pulling of the chain will turn thev given window sash upon its pivotal point, and` for the purpose of holding the 7indow sashes in an open position, the link 36 at thebottom of the chain is connected to the hook 39, 'forthe lower sash and to a similar hook such as 39 shown in dotted lines 1 for the upper sash, the hook 39 being iormedupon thc base 1- connected to the window sill 1,7. and the hook 419 being formed upon or. connected to the transom rail 6. By providing locks for the upper and lower sash railstor thewindow sash, the window sashes can be securely locked in a closed position and held at their tops and bottoms in secured positions with reference to the window frame proper., there by providing a window locking device well adapted for iire protection, owingtotlie fact that at all times the window sash is heldin a Afirm position and the top and bottom rails held in swinging contact with the adjacent parts, to which the tops andv bottom of the sash rails are locked or secured.
